Etymology: "Purifier" is a straightforward formation: the verb "purify" with the agent suffix "-er," which English has used since Old English to name a person or thing that performs an action. The verb itself came into English from Old French "purifier," which was based on the Latin "purificare," meaning to make pure, from "purus" (pure) and "facere" (to make). The suffix has a long path of its own. It descends through Old English "-ere" and Middle English "-ere" from a Latin "-arius" that spread through Proto-Germanic, while the Old French "-ier" form shows how the same Latin ending was also reshaped in French. English therefore has two parallel routes for this ending, one inherited through the native Germanic tradition and one borrowed through French.
